I bought an 18-bottle size second-hand, thinking it would be plenty big enough. It isn't!
If I use a 20-cm mould to press my cheeses, I can fit only one cheese per shelf, ttl 6 cheeses; if I use 12cm moulds, maybe 3 per shelf. OK at first, but when you want to age some cheeses for months or even a year, the shelves soon fill up. If I want to use an aging box I need to remove a shelf, so then there's even less space.
Consider the size of your moulds, the inner dimensions of the wine fridge, and how many cheeses you think you're going to be making. Also what kind of cheeses - aging boxes take up a lot more space than waxed rounds. Then double the number of cheeses
- that's the size fridge you need (for starters....).
